local electric field 中文意思是什麼
local electric field
解釋
定域電場-
In such cases, any local bunching of particles causes a large unshielded electric field unless the density is extremely low.
在這種情況下，除非密度非常低，任何粒子的局部集中都會引起末被屏蔽的強電場。 -
Local electric field effect
局部電場效應 -
Electrical field stress at the icicle tips is even stronger. at these areas, if the electric field across air gaps is high enough, corona discharges are initiated. this can lead to the development of local arcs across the air gaps causing a substantial increase in leakage current and a concomitant melting of ice
空氣間隙的存在使覆冰絕緣子表面的電場分佈發生了明顯畸變，間隙上承受了非常高的電壓，這使得冰凌尖端的電場變得相當強，一旦電場達到了電暈的起始電場，局部放電就在這一區域發生，進而產生局部電弧並逐漸發展成整串的閃絡，泄漏電流迅速增大，同時伴隨著冰的融化。 -
The experimental results show that the surface charging is related with the pre - flashover events, the pre - flashover events can bring the change of surface charge distribution. these may be attributed to the micro - discharge caused by the traps in insulator. the charge carriers can be captured by traps, a space electric field will be set up by the trap centers, and the combined electric field may exceed the breakdown electric field of local area, then the micro - discharge will be initiated
分析表明，反向預閃絡現象與材料的陷阱分佈有關，試樣中電極附近的陷阱中心俘獲載流子后所形成的空間電場的作用是產生這一現象的原因；預閃絡現象和表面帶電現象都是由於絕緣子表面陷阱中心俘獲載流子形成空間電場造成局部場強過強引發的局部放電形成的。 -
The influence of a static electric field was investigated systemic in three stratifications : the electron scope of single atom, multi - atom local effect and macro - materials character based on electron theory. the multi - scope effect of electric field on metals and alloys, such as the atomic energy, solute elements, microstructure and precipitates, fracture character, mechanic and physical properties, were studied with the purpose of finding the mechanism and the nature of the electric field
針對目前電場作用研究中的問題，本文以鋁合金為研究對象，分別在三個不同尺度的理論范疇：單原子的電子理論，多原子（原子團簇）的微觀局域效應，和材料宏、微觀行為，系統的、多層次的研究了電場在電子層次，溶質行為，微觀組織，以及宏觀的斷裂特徵和性能等多個尺度的電場效應。 -
Based on thomas - fermi theory, the effect of external electric field on atomic inner boundary potential was studied. the new atomic potential boundary condition with the influence of external electric field was established and the atomic energy and pressure were calculated with new boundary condition. the local effect of solute element under an electric field was analyzed with the electron shield model
在理論上，基於thomas - fermi理論，重點研究了電場作用對原子體系的內勢場邊界的影響，建立了外場作用下的原子勢場外邊界條件，並計算原子能量和壓強；基於電子屏蔽模型，分析了電場作用下溶質行為的局域效應。 -
We studied the mechanism of the visible light - induced domain switching in the lithium niobate crystals, and considered that the main factor is the movement of light - induced carrier, which modified the local electric field in the crystals and then resulted in the reduction of the domain switching voltage
探尋了可見光誘導鈮酸鋰晶體疇反轉的形成機制，認為光誘導晶體疇反轉的主要原因是光激載流子遷移改變了晶體內部的局域電場，造成了晶體極化反轉電壓的降低。 -
Then virtual dielectric constant method is adopted to calculate the electric field distribution with floating electrodes, and equivalent conductance rate method is adopted to calculate the electric field distribution with surface filth or local puncture in the insulator, furthermore the value scope of virtual conductance rate and equivalent conductance rate are discussed and some useful results are got. for the solution of vortex loss of silicon steel sheets concerning current transformer, the h solution has also been put forward rather than traditional a ? ( p method in order to reduce calculation load
採用虛擬介電常數法計算絕緣子存在懸浮導體的電場分佈，採用等效電導率法計算絕緣子存在表面污穢或局部擊穿情況下的電場分佈。對虛擬介電常數和等效電導率的取值范圍進行了討論，得出了一些有用的結論。對于電流互感器硅鋼片渦流損耗的計算，本文提出了不同於傳統的a -方法的h求解辦法，從而大大簡化了計算。 -
They can dynamically change the distribution of electric field, carriers and current densities in pcss, caused output current to delay and also strengthen the local electric field enough to satisfy qualification of domain, and then cause avalanche. the time of delay is determined by the time of attaining the qualification of domain
非線性光電導開關的時間延遲效應則是由於半絕緣gaas材料中的el2深能級中心動態地改變開關中的電場、載流子濃度引起的；延遲時間的長短主要由滿足成疇所需條件的時間決定。
